Plasticity for user interfaces in mixed reality

Abstract : This PhD thesis focuses on plasticity for Mixed Reality (MR) User interfaces, which includes Virtual Reality (VR), Augmented Reality (AR) and Augmented Virtuality (AV) applications. Today, there is a growing interest for this kind of applications thanks to the generalization of devices such as Head Mounted Displays, Depth sensors and tracking systems. Mixed Reality application can be used in a wide variety of domains such as entertainment, data visualization, education and training, and engineering. Plasticity refers to the capacity of an interactive system to withstand variations of both the system physical characteristics and the environment while preserving its usability. Usability continuity of a plastic interface is ensured whatever the context of use. Therefore, we propose a set of software models, integrated in a software solution named 3DPlasticToolkit, which allow any developer to create plastic MR user interfaces. First, we propose three models for modeling adaptation sources: a model for the description of display devices and interaction devices, a model for the description of the users and their preferences, a model for the description of data structure and semantic. These adaptation sources are taken into account by an adaptation process that deploys application components adapted to the context of use thanks to a scoring system. The deployment of these application components lets the system adapt the interaction techniques of the application of its content presentation. We also propose a redistribution process that allows the end-user to change the distribution of his/her application components across multiple dimensions: display, user and platform. Thus, it allows the end-user to switch dynamically of platform or to combine multiple platforms. The implementation of these models in 3DPlasticToolkit provides developers with a ready to use solution for the development of plastic MR user interfaces. Indeed, the solution already integrates different display devices and interaction devices and also includes multiple interaction techniques, visual effects and data visualization metaphors.
